The first wind turbine at a wind power base in Ulaanqab, North China's Inner Mongolia autonomous region, started to generate power on Thursday, marking success in the first phase of this project.

The wind power base has a total capacity of 6 gigawatts with the first phase completed, and is considered as the world's biggest onshore wind power unit, according to a statement from the company.

Construction on the wind power farm in Ulaanqab began in September 2019 by State Power Investment Corporation. A total number of 1,429 wind turbines will be constructed at this base, and is expected to provide 18,000 gigawatts of renewable electricity to the Beijing-Tianjin-Hebei region annually after the whole project is completed, which could help reduce 15.3 million tons of carbon dioxide emissions, the statement said.
